IMPROVEMENT IN' v('Jl'J'".lTEIR-IEIIELPLD FOR. PLANINGMACHINE.

The Schedule referred to in these Letters Patent and making parl: of the' same.

Ta all whom t may concern:

Be it known that I, DARIUS STEVENS, of.Dai1b11x-y, in the county ot' Fairfield and State of Connecticut, have invented a new and -usetnl Improvement in Molding Cutter-Head; and I do hereby declare that -the following is a'full, clear, and exact description lh'ereof', which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specificaf tion, in which- Y Figure 1 is a top' view of my improved molding cntterhead,the cap-plate being removed, and part of the cutters being broken away to'show theconstruction.v A y g i j Figure 2 is a detail cross-section of tlie saine, taken through Vthe line xa, iig. 1.

Figure 3 is a plan view of one 'of the cutters.y

Similar letters of' reference indicate corresponding parts. 4

My invention has for Vits objectt-o furnish any iinproved cutter-head for holding the cutters for forming moldings, which shall be simple in construction, colfilvenientin use, and will hold'the cutters securely; an

v1t consists'inthe construction of the cutter-head andcap-plates, as hereinafter more fully described.

A is tl|e,cut-terhead,' the faces of which are recessed to receive the cutters B.

.Upon the forward parts of the ends of the faces of the cutter-head A are formed projections or lugs a', the upper sides of which may be soy formed as to correspond somewhat with the outer surface of -the lhe facesof the cutter-heads A, near their forward sides, are recessed-or gl-Coved, as shown in figs. 1 and 2, to receive the screws D, said screws passing in through holes in the ends of the cutter-head A, the lugs c giving suicient strength'. to said parts of the. cutter-heads to prevent the screws from breaking ont.

The' screws Dare Swiveled to the cutter-head A,

turning the screws D in one direction'the nuts E willbe moved forward, and will clamp the cutters B laterally, and by turning the screws D in the other direction the nuts E will be drawn back, releasing `the cutters. p

O are the cap-plates, the forward parts of the ends of which are notched to receive the lugs a', and said f cap-plates are secured to the cutter-head A by the.

bolts F, which are attached to or screwedV into the shoulders at the end parts of the faces of the cutterhcadA, and pass through thel end parts of the capplates C. l

The cap-plates C are secured in' place, clamping the cutters B to the faces of the cutter-heads A by nuts screwing upon the' bolts F, as shown in fig. 2, or by screwing the saidbolts into the said cutter-heads.

1f desired, the lugs c may be omitted, the shoulders of the ends oftheV cntter-heads furnishing suticient strength tov prevent the swiveledbolts from breaking out. In this case the cap-plates donot rcquire to 4be notched.

Having -thus described my invention,

I claim as new and desire to secure by Letters Patent- The combinationand arrangement of' the swveled screws D and sliding nuts E with the grooved cutterhead A, for the purpose of clamping the cnt-ters B laterally, substantially as herein shown and described. DARIUS STEVENS. Witnesses GEORGE H. WILLIAMS, L. P. HOYT.
